NX is a versatile 3D drafting complex that is interconnected with a variety of 3D printing software. Architects and engineers throughout the world use this program to design, analyze, and manufacture objects in a precise and systematic manner. It is vital for entry-level engineering students to familiarize with this multifaceted program to develop their designing capabilities and techniques. This tutorial is intended for novice users of NX and will cover the fundamental commands and techniques to create a simply designed cup. Read each step carefully before performing the action required.

Steps

Part 1

Preparing for Work

1

Create a new model. To do this, select the blank paper labeled "New" in the upper left-hand corner.

2

Adjust properties of the model. Select the "Model" template and set the units to millimeters. Enter a designated filename and click "OK" to begin.

Part 2

Constructing the Base

1

Create a sketch. Start the beginning sketch by clicking "Sketch" in the upper left-hand corner.

2

Classify the plane. Set the XY plane for the orientation of the sketch by selecting the XY axes. Click “OK."

The default axes for NX will be the XY axes (it is represented by a 2-dimensional blue square).

The three orientations in NX are the XY, XZ, and YZ planes.

3

Select a circle as the base shape. Select the circle sketch tool in the “Direct Sketch” window.

The "Direct Sketch" box is adjacent to the "Sketch" command.

4

Adjust the settings. Set the "Input Mode" (under the new window labeled "Circle”) to the coordinate mode by clicking on the "XY" square.

This will manually input the coordinates for the origin.

5

Input the coordinates. Set the X and Y coordinates to zero to ensure the center of the circle is aligned with the center of the axes. Enter "0" in the "XC" row and a "0" in the "YC" row.

When inputting values for the XY coordinates, do not click anywhere on the screen, simply enter “0” then use the “tab” key on the keyboard to alternate to the next row, and enter “0” once again.

To bypass this, click on the intersection of the X and Y axes.

6

Set a diameter. Input “80" into the new window labeled "Diameter" and press enter.

Do not use the cursor during this step, simply type "80" and press enter.

Select the "Extrude" icon. Click the icon "Extrude” towards the upper center of the screen.

The sub-window under the extrude icon contains the revolve command.

9

Extrude the circle. Select the sketch of the circle. Enter a starting distance of “80” millimeters under and an ending distance of “0” millimeters (under the limits section). Click “OK.”

10

Select the "Sketch" icon. Create a new sketch by clicking the previously used “Sketch” icon.

11

Specify the orientation. Hover the cursor over the top of the cylinder until the heading “Face of Extrude” appears (when it appears, click on the cylinder to select the planar face). Press “OK."

The top of the cylinder will become red when setting the planar face to “Face of Extrude.”

12

Use the circle tool. Select the circle icon used previously (in the window labeled “Direct Sketch").

13

Set the origin of the circle. Specify the center of the circle by entering “0” in the “XC” row and a “0” in the “YC” row. Press enter.

14

Set the diameter. Input “74” for the diameter and press enter.

15

Finish the sketch. Select the "Finish Sketch" icon; that should be adjacent to "Sketch."

16

Start a new extrusion. Select the “Extrude" icon.

17

Change the extruding settings. Select the newly created inner-circle sketch as the curve to extrude. Change the direction of the extrusion by selecting the “Reverse Direction” icon located under the subheading “Direction.” Input “74” as the starting distance and click “OK.”

Part 3

Sculpt the Cup

1

Use the edge blend command. Select the edge blend command to the right of the "Extrude" icon.

2

Select the outer edge of the cylinder. Click on the outer-most ring of the cylinder to set the edge.

3

Change the specifications of “Edge Blend". Switch the default from G1 (Tangent) to G2 (Curvature) under the options for “Blend Face Continuity". Set the “Radius 1” to “5”, and set “Rho 1” to “.3”. Click “OK.”

4

Use the edge blend command once again. Select the "Edge Blend" icon.

5

Select the outer edge of the bottom of the cup. Then, click on the outermost edge at the base of the cup.

6

Change the specifications of “Edge Blend.” Under the options for “Blend Face Continuity”, switch the previously used (“G2 (Curvature)”) back to the default, G1 (Tangent) under the options for “Blend Face Continuity”. Leave the default for “Shape” and set the radius to 12.

Part 4

Finishing the Cup

Add a file name. Add a file name to the object and save as a .prt file. Click "OK."
